In this article, firstly the background of the textile trade conflicts within sino - us or sino - euro are introduced, thus learn that how to discern and dodge the foreign trade risks, how to choose the appropriate investment projects have already become one of the most important questions for exporting companies on foreign trade affairs well - known as high investment and high risk. so the main text makes a risk analysis qualitatively and quantitatively on a textile - exporting trading company from three angles of statistic 、 game theory and portfolio theory, which is the main content that we studied. firstly, the statistic article adopts data of the transaction closing price of the textile clothing index in shenzhen stock exchange at the end of each quarter as well as several other kinds of data reflecting the macro - economic changes, performs an empirical analysis of these data according to the theory of co - integration test 、 granger cause test and impulse response function of time series in economitric, and learn that the impact to ti is more obvious by the economic index reflecting local commodity price level and economic prosperity degree home and abroad, as well as the impact degree and the time lag degree, and knows the macro - economic risks faced by textile business enterprises ; after that by the game theory angle we analyze exactly the managing risks faced by one textile export corporation named beauty. from the game expansion chart the system arrangement between censor ways by exportation goal countries and exporting strategies by the exporting enterprises has been analyzed. involving the benefit assignment between them both the limited rounds and infinite rounds negotiations of cooperation games have been studied, and then country responsibility and the enterprise managing risks on foreign trade affairs and so on have been analyzed exactly ; in order to realize the investment multiplication in the certain degree to disperse the risk, the
本文首先介紹了中美、中歐紡織品貿易爭端的來龍去脈,由此可知在涉外貿易這種以高投入、高風險著稱的行業里,如何甄別和規避外貿風險、如何選擇合適的投資項目已經成為外貿企業的首要問題。因此,正文分別從統計學、博弈論和投資組合三種角度對涉外紡織品貿易公司風險進行了定性和定量的分析,這也是本文的主要研究內容。首先,統計學篇選取了深圳證券交易所行業分類指數?紡織服裝指數( ti )每一季度末的交易收盤價和若干種反映宏觀經濟變化的指標,利用計量經濟學中時間序列的協整檢驗、 granger因果檢驗和脈沖反應函數等理論做實證分析,從而得知反映國內物價水平和國內外經濟景氣程度的經濟指標對紡織板塊上市值的沖擊比較明顯,且可知沖擊程度和時滯度,進而分析出涉外紡織企業所面臨的宏觀經濟風險;接著,從博弈論的角度具體分析一家紡織品出口公司( beauty )的外貿活動所面臨的各種經營風險,該篇從博弈擴展圖入手,分析了出口目的國審查方式與本企業出口策略之間的制度安排;並圍繞雙方的利益分配,研究了有限回合和無限回合合作談判博弈,然後具體論述了國家責任和企業涉外經營風險等問題;在一定程度上為了實現投資多元化來分散風險的目的,投資組合篇從經典的markowitz模型著手,在一些特定條件的限制下,給出了一個相應的投資組合模型。After we have a superficial realization through comparatively studying legislation example of different countries and zones, this thesis begin to probe into me rule ' s principal and theory basis. stability of the decisions and respect the procedure are two principals that must be followed defending stability of the decisions is beneficial to defend stability of law relations that are caused by decision of shareholders, defend the deal safe, promote the efficiency of the companies. respecting the procedure is beneficial to present the value of the procedure, guarantee the rights and interests of shareholders from the procedure. theory basis of deciding grounds of action and dividing the kinds of action make up theory basis of the rule of rescuing laws on decision of shareholders. the final define of grounds of action that breaking the law and the constitution of company is decided by the nature of company law and the nature of constitution of company. on the nature of company law, there are some disputes, include forced law opinion, willfully law opinion and synthetic opinion considering present company law, i think the synthetic opinion is right the nature of constitution of company has two features : self - rule and ruled by law. in general, constitution of company is a kind of self - rule law that partly ruled by law
此外,本文還討論了確認決議不存在之訴與不當決議取消、變更之訴的存在價值,綜合考慮后,決定保留確認決議不存在之訴,廢除不當決議取消、變更之訴這一弊大於利的訴訟類別。除了總體探尋股東會決議瑕疵救濟制度的理論依據外,考慮到召集制度和決議方法在股東會決議制度上的重要性和二者具體內容的繁雜,本文還重點分析了召集制度上的瑕疵和決議方法上的瑕疵兩大訴由。另外,本文創設了「決議顯著不公正」這一新訴由以防止多數決的濫用,多數決的濫用多年來一直是股東會決議中的一大頑癥,但各國公司法卻一直對其缺乏明確的規制,筆者希冀以多數決的濫用造成決議顯著不公正這一現象作為訴由,並提出具有可操作性的標準,由法官裁量判斷是否構成多數決的濫用,以期彌補股東會表決制度上資本多數決原則的不足。The main reasons are : the first, some characters influencing the risk of driving and the number of accidents that may be happen are not measurable, such as the well - trained degree of the drivers, the concentration degree of the attention during the driving hour, the speed of the reaction and the accuracy of the judgment in the nervous circumstance ; the second, because the classification variables are limited, the measurable characters of the risk are impossible to be contained in these variables ; the third, because of the existence of the moral risk, it very difficult to affirm that the classifying of the policyholders is right
其主要原因為:第一、一些影響駕駛風險或出險次數的因素是不可度量的。例如駕駛員的駕駛熟練程度,駕駛時注意力的集中程度,在緊張情況下做出反應的速度以及判斷的準確性等;第二、由於分類變量有限,可度量的因素也不可能全部包含在這些變量中;第三、由於道德風險的存在,對投保人的分組很難肯定是正確的。如有的國家的機動車保險中要求投保人告知他們的年行駛里程數,在這種情況下,保險公司很難採取什麼措施避免投保人的故意低估。Comprehensive parametric recognition method is proposed. the method works in this way. firstly, basic data are obtained form laboratory tests or back analysis then initial result is obtained through empirical judgement, engineering comparison, at last, the rheological parameters. used in computation are obtained after comprehensive analysis and judgment

由於實際工程巖體其固有的非線性和復雜性,使得求解對應的諸如其穩定性、變形等問題面臨較大的困難,而有關的工程結構的設計必須保證該結構在外來因素的作用下具有足夠的安全度、經濟性和合理性,這必然要求對巖體及其工程結構的受力與變形有一套量化評判體系和優化技術,抓住實際工程問題的本質特徵並建立可行的符合幾何模擬、本構模擬、受力模擬、過程模擬四原則的求解模型,通過該模型的數值模擬成果來指導巖體工程的設計、施工及運營、管理;而巖體結構面的存在使得基於傳統連續介質力學理論的理論分析和數值模擬面臨巨大的挑戰,物理模擬的試驗周期和成本也大大增加,而巖土體工程問題則成為典型的數據有限、了解程度有限類問題,這類問題的解決需要綜合應用理論分析、經驗判斷、物理模擬和數值模擬等方法,數值模擬可以完成目前許多技術手段無法完成的實驗,如參數控制,復雜條件下的邊界條件的處理,同時數值模擬具有高可重復性,且數值模擬的成本和人力開銷等遠低於物理模擬,因此研究巖土體工程問題的流形元數值模擬方法是一項具有理論和實際工程應用價值的重要課題。According to a real ac vf asynchronous dynomometer system, first step, the paper deducts the mathematic model of the system, and analyzes the system stability on the basis of the ? irst method ? of lyapunov stability, then draws the eigenvalues of the system under the situation of the variation of different parameters, and results in finding the changing regularity of the system stability caused by varitation of variant system parameter ; secondly, sets up a system simulation model in terms of a real power feedback ac vf asynchronous dynomometer system, and emulates different running states of the system, not only analyzes methods of adjusting parameters to improve the working performance in the field of weak flux of the system, but also proves the effectiveness of the methods via simulation ; at last, compares the simulation results of the model with the experiment results of the real system, and show the nearly correctness of simulation system, and also confirms the practical usage of the simulation system as an effectively assistant tool in the process of developing and design a real dynomometer system
